Consider two reactions. Reaction (1) has a constant half-life, whereas reaction (2) has a half-life that gets longer as the reaction proceeds.
What can you conclude about the rate laws of these reactions from these observations?
a.The first reaction should have a first or a second order, the second one should have an order greater than second.
b.The first reaction is a first order reaction, the second one has a second order.
c.The first reaction should have a first or a second order, the second one should have an order not less than second.
d.The first reaction is a first order reaction, the second one should have an order greater than first.
adding a few drops of a strong acid to water will lower the pH appreciably. however, adding the same number of drops to a buffer does not appreciably alter the pH. why
You could determine Ka for benzoic acid by measuring the pH of a 0.010 M solution of benzoic acid. Why is graphical method (pH vs volume of NaOH added) a better way of determining Ka
